short supplies to start, everyone knew the war was just about over. A fighting retreat with no time to service weapons, the Chinese right on top of you all the time, lubrication probably the consistency of karo syrup, if you had any, and cold, cold, cold.
Does anyone know how the M1 Carbine faired in the Battle of the Bulge in the Winter of 1944-45? Were there similar malfunctions?
If there weren't similar failures in the Ardennes I suspect an ammo problem
